1 Claim.

My invention relates to burial vaults and it has for its object to improve the construction thereof, particularly with respect to the inner -sides of the walls thereof.

Heretofore it has been the practice to paint or coat the interiors of concrete burial' vaults with asphalt to exclude water and dampness thereby to protect its contents, but it has been found that the asphalt, as heretofore applied to the interior, would in a comparatively short time `settle, flow or creep downwardly on to the floor or bottom of the vault, which was objectionable.

My invention provides a concrete vault of the character described with an interior waterproof facing or lining including asphalt or the like, which is so constructed and incorporated in the vault structure that it constitutes an integral permanent part of thelatter and will not creep or settle in the objectionable manner referred to.

20 In the accompanying drawing:

Figure l is a cross-sectional view of one-half of a burial vault constructed in accordance with my invention, the omitted half being a counterpart of that shown.

Figure 2 is a magnied cross-sectional View of a portion of one of the walls of the vault shown in Fig. l.

Figure 3 is a cross-sectional view of a mold for use in producing the body or base of my improved vault, certain elements forming parts of said body when comileted being shown in position therein.

As shown in Fig. l my improved burial vault comprises a base or body section A and a cover section B. Each of these two sections comprises a molded body I of concrete; a metallic reinforcement II embedded, as usual, within t'he concrete body It, and a lining I2, the latter forming a permanent and integral part of the body Iii.

As shown in the magnied sectional View of Fig. 2 the lining I2 is a laminated structure comprising a sheet i3 of felt or other suitable fibrous material thoroughly impregnated with, and completely embedded within, a thicker sheetor body of asphalt l-i, and a layer I5 of stone granules adhesively applied to one side of the body of asphalt I4.

In producing this lining I2 the felt layer I3 ls first combined with the body of asphalt It as shown and thereafter, while the asphalt is in a more or less heated and sticky condition, a lay'er of stone granules I5 such as slate is applied to one face of the body I4 and then rolled or otherwise pressed into and against the asphalt so that they become adhesively attached thereto. This 55 laminated material is the same as that heretofore employed in making roofing shingles.

In producing my improved burial vault I employ a mold illustrated in Fig. 3 which includes a core I6 supported by a base Il upon the top of which latter is also applied an outer box-like mold i8. Before placing the outer mold I8 in position the exposed exterior of the core IB is 5 covered with the laminated material IE-lli-I which is indicated at I2 in Figs, 1 and 3 .of the drawing, which may be secured in position by means of wires I9 wrapped around the same and each tied or twisted together at its opposite ends. 10 Then the metallic reinforcement i! is placed in position around the core i6 and above the same after which the outer mold section I8 is placed in position upon the base il. The metallic reinforcement II is spaced away from the opposite side walls of the mold cavity as usual. Aite-r assembling the parts in this manner the concrete is poured into the mold cavity thus casting the body section A in an up-side-down position. l

As shown in Fig. 2, the concrete enters and 20 fills all oi the multitude of depressions and cavities which exist upon the outer granular Iside or face of the lining material I2 and as a result thelatter is permanently and xedly united with the concrete. Because of the presence of the 25 asphalt saturated felt or fibrous lamination i3 within the layer M, Fig. 2, said iibrous material permanently holds the asphalt of the lining material against creeping downwardly under the influence of heat and gravity and the interlocking 30 of the concrete with the outer granular surface of the lining material also (zo-operates with the material in holding the asphalt xedly `and permanently in position.

lt will be clear that in producing the cover B 35 anappropriate mold is usedwithin which the lining material I2 and the reinforcement il are assembled before pouring the concrete much the same as described in connection with the producnon of the body A. 4

What I claim is:

A molded concrete burial vault section cemprising a bottom wall; oppositely disposed upright side walls` and oppositely disposed upright end Walls; an inner lining covering said walls con- 45 sisting of a pre-formed laminated product comprising a sheet of brous material embedded within and impregnated by a layer of asphalt to the outer face of which is adhesivelyv and permanently applied a layer or covering of stone 50 granules, and each of said walls also including an outer body of concrete that is permanently interlocked with the granules forming the outer face of said lining material, and a cover for closing the top of said section.
